"Who are they?" Julia asked.

Rachel Griffith, one of her two permanent bodyguards, was sitting in the jump seat opposite. A twenty-five-year-old security division hard-liner, wearing a smart blue two-piece suit. She turned round, scanning the road ahead. Her lean face flashed Julia a quick reassuring smile. "Just some protesters," she said. "You and the Prime Minister at the same event is a publicity opportunity they can't ignore."

Julia nodded. Rachel had been with her for five years, tough, smart, and loyal. She liked to think of her as a friend as well. If Rachel wasn't worried, there was nothing to be worried about.

"This is as near to the Institute as they can get," said Morgan Walshaw, Event Horizon's security chief, from the second jump seat. Even sitting, he couldn't appear relaxed, spine stiff, shoulders squared, wearing an immaculate charcoal-grey suit. He fitted her conception of a crusty old retired Home Counties general perfectly. Except Morgan was far shrewder than any general. Thank God.

He was sixty-two years old, silver-grey hair clipped down to a centimetre from his skull, the thick, tanned skin of his face heavily crossed with narrow lines, hard-set light-blue eyes which always made her feel incredibly guilty whenever he stared at her. Everything she did eventually filtered back to him: nights out with her girl friends in Peterborough's clubs, holiday adventures, party antics, boys. Morgan had been with the company for years, protecting her grandfather, and now her, a job he performed with superb efficiency and complete devotion. His approval was always tremendously important to her, mainly because he would never make a gratuitous compliment. She had to earn it, something that never happened with most of the people in her life. And words of praise had indeed been awarded, albeit grudgingly, with more frequency in recent years. She often caught herself wishing he was her real father. The knowledge that he would be retiring in a few years was something she always tried to bury right at the back of her mind; it was a horrifying thought.
